"Viewport Options" are not exposed in the Inspector when SVG is imported as UI Toolkit Vector Image

How to reproduce:
1. Open the attached “IN-138246” project
2. Select the “personsmall.svg” asset
3. In the Inspector, switch the “Generated Asset Type” to “Texture2D”
4. Observe the Inspector

Actual result: There is no way to change “Viewport Options” for the “UI Toolkit Vector Image” generated asset type unless you switch the type to “Texture2D”
Expected result: The “Viewport Options” option is exposed for the “UI Toolkit Vector Image” generated asset type

Reproducible with: 6000.3.0a5 (36d7e9fd6645), 6000.3.12f1, 6000.4.1f1, 6000.5.0b1 (c1f81ff5b082), 6000.6.0a1 (7dc703ab9bd8)
Not reproducible with: 6000.0.72f1, 6000.3.0a4

Reproducible on: macOS 15.7.4 (by user), Windows 11
Not reproducible on: No other environments tested

Notes:

• “personsmall.svg” asset is imported as a UI Toolkit Vector Image with Basic Triangulation
• The default “Viewport Options” option is “Don't Preserve Viewpoint" thus SVG images are cropped to their content when imported as “UI Toolkit Vector Image”
